In the t-shirt there must be the first picture attached( it represents some pokemon but they're not drawn properly), you have to draw it again replacing to each creature a pokemon, i suggest you to watch the pictures on google for each pokemon, so you can draw it better.I'll write you below the substitution you have to make:
- The Creature with the white aura color is called: Eevee (This is the basic pokemon that come from the left part of the triangle, all the others pokemons on the right part are the evolutions of this one )
- The Creature with the red aura color is called : Flareon ( Type : fire)
-The Creature with the yellow aura color is called : Jolteon ( Type : thunder)
-The Creature with the green aura color is called : In the game this pokemon doesn't exist, so you have to draw it using your creativity ( Type: it should be like grass )
-The Creature with the sky blue aura color is called : In the game this pokemon doesn't exist, so you have to draw it using your creativity ( Type: it should be like ice)
-The Creature with the blue aura color is called : Vaporeon ( Type: water)
-The Creature with the violet aura color is called : Espeon ( Type: Psycho)
-The Creature with the black aura color is called : Umbreon ( Type: Darkness)
The picture has to cover a great front part of the t-shirt, so i suggest you to draw the left pokemon in the low part of the t-shirt and link it with a white aura to the left part of the triangle ,so you can move the triangle a little bit to the left and so you have more space to draw in a detailed way the most important part of the picture : all the pokemon on the right.
The background is really important and you have to draw it according your style and creativity.
